Etymology: Eviota: No etymology given, suggested by Christopher Scharpt: from Latin 'eu' for 'true' and 'iota' for anything very small, in combination 'truly very small' referring to it as being the smallest vertebrate at the time it has benn described by Jenkins (thus, making the suggestion by Scharpt plausible.; rubriceps: Name from combining the Latin rubrum (red) and caput (head), referring to the distinctive red head in life; an adjective.

soft rays: 7 - 8;
Vertebrae: 25. This species is distinguished from its congeners by the following set of characters: cephalic sensory-pore system pattern 2 (only IT pore missing); dorsal/anal fin-ray formula almost always 8/7; pectoral-fin rays unbranched; first three dorsal spines may be filamentous in males; 5th pelvic-fin ray absent or rudimentary to 20% maximum of 4th ray; strong black pigment along scale pockets on ventral two-thirds of sides and peppering of dark chromatophores on nape and upper back when preserved; snout, top and sides of head red in life; dark area of abdomen not crossed by a curved yellow-gold line in life (Ref. 88933); characterized further by longitudinal scale series 21-24; scales ctenoid, none on head, breast and pectoral fin base; depth of body 4.2-5.6 in SL (Ref. 90102).
